question

A guitar string creates a sound wave of known frequency. Which of the following describes a correct and practical method of measuring the wavelength of the sound wave with a meterstick?

choices

  1. Lightly touch the guitar string in the middle such that a single node is created. Measure the length of the string; this is the wavelength.
  2. Measure the length of the guitar string; this is half the wavelength.
  3. Adjust the length of a pipe placed near the string so that resonances are heard. Measure the difference between the pipe lengths for consecutive resonances; this is half the wavelength.
  4. Measure the peak-to-peak distance of the wave as it passes; this is the wavelength.
